Jonah collects rainwater in a large barrel that weighs 30 pounds. When there are 10 gallons of water in the barrel, the total we

Serjik [45]

The first thing we are going to do for this case is define variables.
We have then:
x: number of gallons of water
y: total weight
We then have an equation of the form:
$y-yo = m (x - xo)
$
Where,
$m = (y2 - y1) / (x2 - x1)
$
Substituting values:
$m = (196.8 - 113.4) / (20 - 10)

m = 8.34$
We choose an ordered pair:
$(xo, yo) = (10, 113.4)
$
Substituting values:
$y-113.4 = 8.34 (x - 10)
$
Rewriting:
$y = 8.34x - 83.4 + 113.4

y = 8.34x + 30$
Answer:
y = 8.34x + 30
